NaOH and O2 are formed when Na2O2 reacted with water by reaction:2Na2O2 + 2H2O = 4NaOH + O23.2 g of O2 corresponds to 0.1 mol of O2Thereby, the quantity of NaOH is 4*0.1=0.4 molThe mass of NaOH is m(NaOH) = M(NaOH)*n(NaOH) = 40g/mol * 0.4 mol = 16 gAnswer: 16 grams of NaOH are produced when 3.20 grams of O2 is formed.
